Idea 1 Smybiote akame

As the title says basically an mc from our world is sent to akame ga kill as a symbiote and merges with akame. I had several ideas on how this would of went.

Idea one akame finds mc and merges with it and everybody thinks mc is an teigu

Idea two like the first one but a darker route akame finds mc but mc merges with akame taking over her body becoming akame the symbiote queen or king. It really doesn't  matter symbiots or agender. Using  the an ability similar to carnage to take over the empire.
